Abstract (en)
[origin: EP2722648A2] The device (1) has a first subassembly including a measuring standard i.e. scale, on which a code track is placed, and a scanning unit scanning the track in measuring direction to produce position signals to generate absolute digital position. A second subassembly includes a peripheral unit to perform additional and/or auxiliary function of the device. The first subassembly and the second subassembly are connected to each other by a set of electric lines to transmit electrical signals. The first subassembly exclusively includes components used in a radiation area (A) of a machine. An independent claim is also included for a measuring system.
